A Typology of Cost Accounting Practices Based on Activity-Based Costing – A Strategic Cost Management Approach and a Case Study
2018
This paper examines cost accounting methods containing one or more activity-based costing (now ABC) like dimensions. The research reviews these methods since the early stages of ABC. The objective is to analyze cost accounting proposals with, in part, a philosophy reminiscent ABC. For all the methods examined, ABC is a starting point at least one important component. The research purposes are to analyze the strategic dimension of the methods described and to build a typology useful for managers. Factors of usefulness are considered in the paper. The discussion leads to a four-dimensional typology based on three strategic objectives assigned to the cost accounting systems. The foundation of …
Du verbe instrumental dans la musique subsaharienne
2021
Sub-Saharan music results from the spoken language/instrumental language relation, directed by an oral culture. In this culture, these languages transmit ? beyond their singularities ? messages thanks to either a coded signal known by the linguistic community or previously defined among a group of individuals, or is used as a true meta-language copied on the articulated and usual language used every day. Here, an instrumental musical speech can then imitate and reproduce the tonal inflexions of the language to make its matter understandable. This fact is the natural result of a strong interaction and interrelation between the spoken language and the music as well as the conception that the …
El sedentarismo en los adultos mayores del entorno rural: estrategias de entrenamiento concentrado versus distribuido
2019
Mejorar la salud de manera integral y reducir el sedentarismo es un reto actual en los adultos mayores del entorno rural. El objetivo principal de este estudio, eje de la campaña Buñol se mueve contra el sedentarismo, fue analizar el impacto de un programa de paseos saludables "PSAM" versus un programa de entrenamiento multicomponente "EFAM-UV©" (3 y 2 sesiones/semana respectivamente); siguiendo en ambos casos dos distribuciones de entrenamiento diferentes: concentrada (CON: 60 min/sesión) vs distribuida (DIS: 30 min por la mañana, 30 min por la tarde). Se realizó un estudio cuasi-experimental y longitudinal (15 semanas) con un diseño factorial 2x2, donde participaron 48 adultos mayores ina…
Influencia de la exposición femenina a compuestos ambientales y procedentes de la dieta sobre los resultados del tratamiento de fecundación in vitro
2022
En las últimas décadas se han observado menores tasas de fertilidad, fundamentalmente en regiones industrializadas, lo que ha incrementado la necesidad de recurrir a técnicas de reproducción asistida. Entre los factores responsables de este descenso de la fertilidad humana se han incluido tanto factores socioeconómicos como factores ambientales y de estilo de vida, entre los que se incluye la exposición a factores ambientales y procedentes de la dieta. Aunque su influencia ha sido bastante estudiada en hombres, su impacto sobre la fertilidad femenina se encuentra mucho menos evaluada. Por lo tanto, el objetivo de la presente tesis ha sido evaluar las concentraciones de fitoestrógenos (daidz…

Growth and defense in deciduous trees and shrubs under UV-B
2005
Abstract Reflection by waxy or resinous surface structures and hairs, repair reactions of biomolecules and induction of different sheltering components provide the means of plant protection from harmful solar UV-B radiation. Secondary products, especially flavonoids and phenolic acids as defense components are also important in plant tolerance to UV-B, fulfilling the dual role as screens that reduce UV-B penetration in plant tissues, and as antioxidants protecting from damage by reactive oxidant species. Plants are sensitive to UV-B radiation, and this sensitivity can be even more clone-specific than species-specific. The results available in the literature for deciduous trees and shrubs in…
Complex-Valued Independent Component Analysis of Natural Images
2011
Linear independent component analysis (ICA) learns simple cell receptive fields fromnatural images. Here,we showthat linear complex-valued ICA learns complex cell properties from Fourier-transformed natural images, i.e. two Gabor-like filters with quadrature-phase relationship. Conventional methods for complex-valued ICA assume that the phases of the output signals have uniform distribution. We show here that for natural images the phase distributions are, however, often far from uniform. We thus relax the uniformity assumption and model also the phase of the sources in complex-valued ICA. Compared to the original complex ICA model, the new model provides a better fit to the data, and leads…
1H-naphtho[2,1-b]thiete and 2H-naphtho[2,3-b]thiete- synthesis and reactivity
1994
Abstract The title compounds 4 and 8 are obtained by flash vacuum pyrolysis of the corresponding hydroxymethylthionaphthols 3 and 7. Whereas 4 shows a smooth ring opening on heating, 8 is thermally stable but reacts photochemically. The different behavior is explained on the basis of an MNDO calculation. The valence isomers 4′ and 8′ represent thioquinonemethides, which are highly reactive components in [12π + 2π]cycloaddition processes (4 → 9, 10, 11; 8 → 12).
